We want to help you fix your WordPress admin speed and it is recommended to follow the steps to avoid impacting your WordPress website in a negative way.

Solve WordPress Admin Slow With Better Web Hosting

This is probably NOT the answer you are looking for, but trust us. One of the most common culprits to a slow loading WordPress backend is because you use a sub par web hosting service.

There are two scenarios that may lead to this issue:

  • Your host just plain doesn’t have the web hosting performance you are looking for (or what they had promised you with)
  • You might have a quality host, but you’ve outgrown the plan that you’re on

Either way, if your web hosting company can't keep up with your website, it will almost certainly lead to a slow WordPress admin dashboard (and heck, you might even have a slow front-end, too).

There are seven more fixes in this post; some are fast fixes and some are challenging fixes which will help you solve a slow loading WordPress backend. But sometimes the only fix is to crack open your wallet and upgrade hosts.

2. Use Query Monitor And P3 Plugin To Find Slow Plugins

Slow Plugin Makes WordPress Admin Slow

One of the best ways to make your WordPress dashboard faster is to understand the issue(s) that leads to a slow loading site.

Do you remember the first time you install WordPress? Your dashboard loads lightning fast but as you installed more plugins, it started to slow down, right?

Now, let’s dispel with a myth – “more plugins” does not automatically mean a slower site or WordPress admin…

But “more resource heavy plugins” does.

So, how do you find plugins that are using a lot of resources?

The answer is to use either Query Monitor or P3 (also known as Plugin Performance Profiler).

Both of these plugins can be found in WordPress repository and once installed and activated, you can run simple tests to determine the plugin(s) that is affecting your website loading speed.

If you find a slow plugin, we recommend you to disable and deleting the plugin. If you need to use the plugin, you should find a better performance alternative plugin (or hard coding the functionality).

3. Clean Your WordPress Database To Remove Unwanted Files

Clean Up WordPress Database To Speed Up WP Admin

You can solve the slow loading WordPress admin (even today) by cleaning out your database. A WordPress database will increase in size (by default) over time due to the number of post revisions, transients, etc. If you are managing WooCommerce stores, you will find even more expired transients in your database!

Most of these data can be safely deleted to remove this bloat without affecting your site in anyway.

There are two tools to clean up your database for a faster WordPress backend:

Both of these allows you to remove unwanted data from your database and help manage the size of your database (by making everything tidier).

4. Use The Latest Version Of PHP

Use Latest PHP Version To Solve Slow WP Admin

It is important to understand that this solution to a faster WordPress backend requires some level of server knowledge. Changing the PHP version without doing any backup can make your website inaccessible.

Generally, WordPress is built with PHP, but the exact version of PHP that your site is using depends on which version of PHP is installed on your server.

Often times, newer versions of PHP offer better performance improvements and improved security features. The WordPress core team understands this and is constantly encouraging WordPress users to update to the latest PHP versions.

Recently, Kinsta made public with the discovery that PHP 7.3 can handle more than triple the number of requests per second that PHP 5.6 can handle. Take a look at the image below.

Despite the massive performance in the latest PHP version, most WordPress users are still using PHP 5.6 (or older).

In order to upgrade the PHP version, you need to login to your web hosting backend and perform simple tasks. Here's what it looks like if you are hosting on Kinsta:

It is common that some web hosting company do not allow you to change or update the PHP version from the hosting backend. In this case, you need to reach out to your host's support staff for help. If by any change your host does not support PHP 7+, this is a sign to switch host right now!

5. Increase The Memory Limit To Make WordPress Admin Faster

How To Increase PHP Memory Limit For WordPress

Here's the truth. Most web hosting companies hate it when you request for a memory limit increase. This step is important because at times, your WordPress admin dashboard is hitting a bottleneck because of your WordPress site’s PHP memory limit.

If this is the case, increasing your website memory limit can sometime (not all the time) fix the issue.

Now, we are aware that some web hosts allow you to increase the PHP memory limit by yourself. To increase the memory limit head over to your wp-config.php file and add this line at the top:

define(‘WP_MEMORY_LIMIT’, ‘256M’);

If your web host doesn't allow you to change and update the PHP manually, reach out to the support and ask for some help.

If you are non-techie, this method would be the easiest for you to improve the WordPress admin loading speed.

The WordPress CMS allows you to control how many posts, pages, or custom post types to display at a time (including things like WooCommerce products, orders, etc.), via the Screen Option setting as seen above.

We recommend you to remove as many widgets as possible (those which you don't require) to speed up the WP Admin loading time.

Always remember that, "Less is more" when WordPress speed is a concern.

7. Disable Cache Setting In WP-Admin And Administrator Roles
